Title: Process for the improvement of textiles and the like by rendering the same resistant to attack by textile pests, bacteria and mould
IPC: A01N57/00
Filed: 1929-05-14
Abstract: 312,163. I. G. Farbenindustrie Akt.- Ges. May 21, 1928, [Convention date]. Proofing against vermin.-Fabrics and the like are proofed against moths, mould, bacteria, &c. by treatment with a salt of a quaternary phosphonium base applied in a dilute aqueous or other solution. After this treatment the fabric may be treated with another salt interacting with the phosphonium salt to produce less soluble salts. Carboxylic, hydroxycarboxylic, sulphinic or sulphonic acids or inorganic acids such as sulphuric or hydrogen halide acids may be used in forming the salts from the phosphonium base. The four other substituents may be all the same, for example as in tetraethylphosphonium iodide, tetraphenylphosphonium bromide or tetraisobutylphosphonium sulphate, or they may be different, as in benzyltriethylphosphonium chloride, naphthyltriethylphosphonium iodide, p-chlorobenzyltriphenylphosphonium chloride, ethyltritolylphosphonium iodide and ethyltrixylylphosphonium iodide. Other salts specified are benzyltriphenylphosphonium nitrate, methyltriphenylphosphonium iodide, ethyltriphenylphosphonium bromide, hydroxyethyltriphenylphosphonium chloride, ethylene-di-triphenylphosphonium bromide, p-xylylene-di-triphenylphosphonium bromide, pentamethylene-ditriphenylphosphonium bromide, o-chloro-benzyltriphenylphosphonium chloride, p-nitro-benzyltriphenylphosphonium chloride, w-carbethoxymethyltriphenylphosphonium chloride, anhydrow-carboxymethyltriphenylphosphosphonium chloride (internal salt), tetraphenylphosphonium bromide and allyltriphenylphosphonium chloride. In an example 100 kgs. of wool are treated with 300 litres of a 0.3 per cent solution in alcohol or water of benzyltriphenylphosphonium chloride. The material thus treated may be treated subsequently with a solution of potassium perchlorate whereby practically insoluble benzyltriphenylphosphonium perchlorate is produced on the fibre,. In another example material treated with chloro cresotinic acid anilide sulphonic acid is after-treated with a solution of benzyltriphenylphosphonium sulphate. In another example the material is sprayed with a 2 per cent solution of benzyltriethylphosphon. ium chloride in alcohol or other organic solvent. In a further example furs are rolled in a drum for an hour with a mixture of 10 per cent p-chlorobenzyltriphenylphosphonium chloride and 90 per cent talcum. Specification 303,092 is referred to.

Abstract: 1,150,656. Synthetic resin laminates. Y. KAWAMURA. 6 June, 1966, No. 15385/68. Divided out of 1,150,654. Heading B5N. A method of manufacturing a synthetic resin structure from two laminar synthetic resin outer wall members and at least one intermediate member, each outer wall member having a first layer of a softenable synthetic resin and a second layer of a different synthetic resin and the or each intermediate member comprising at least one layer of a softenable synthetic resin, comprises the steps of positioning the or each intermediate member between the outer wall members so that the or each intermediate member contacts a portion of the first layer of each outer wall member or a portion of an adjacent intermediate member, and treating the wall members such that the first layers soften and adhere to the intermediate member. In one embodiment, Fig. 1, outer wall members are spaced by one planar and two corrugated intermediate members, the members comprising layers 1, 2, 3, 4 and 5 of a low softening point material, and layers 6, 7, 8 and 9 of a relatively high softening point material, and being joined by softening the lower softening point material by heat. In a second embodiment there are two outer wall members and an intermediate honeycomb which consists entirely of low softening point material, and in a third embodiment two outer wall members are spaced by a corrugated member in which the crests of the corrugations zig-zag. A solvent may be used instead of heat to soften the first layers. As low softening point materials may be used (a) P.V.C. or polyvinylidene chloride, (b) low density polyethylene, or ethylenevinylacetate copolymer, (c) polystyrene and (d) polypropylene or polycarbonate, the corresponding high softening point resins being (a) polystyrol, cellulose ester, A.B.S. copolymer, polyacetal, polycarbonate, or polyolefine, (b) medium or high density polyethylene, polypropylene or polystyrene, (c) polypropylene, polycarbonate, or phenol resin, and (d) cellulose filled phenol resin, polyester, epoxy resin, urea resin and melamine resin.

Title: Hydraulic adjusting mechanism particularly for brakes
Inventor: OSWALT BURLIN WILLIS
IPC: F16D65/74
Filed: 1958-05-14
Abstract: 833,857. Hydraulic brakes. GOODRICH CO., B. F. May 14, 1958, No. 15499/58. Class 103 (1). In a brake-adjusting mechanism for hydraulic brakes, a cylinder 18 is placed in each line 13, 14 leading from the master cylinder 11 to the wheel brakes 15; the cylinder comprising a main piston 25 interposed between the inlet 23 and outlet 24 of the cylinder 18 and a valve means 36 provided in the main piston 25 to permit adjustment of the volume of fluid in the fluid link between the main piston 25 and the wheel brake cylinder to adjust the brakes. In operation, fluid from master cylinder 11 moves main piston 25 to the left and displaces fluid to actuate the brakes. If, however, brake lining wear has taken place, an increased volume of fluid will be required to actuate the brakes fully and under these conditions the pressure applied to the piston portion 35 of the valve means 36 through openings 45 will be effective to lift valve means 36 and permit fluid to flow through openings 45, 41 and 27 to increase the volume of fluid in the link between the outlet end of cylinder 18 and the wheel brake cylinder until a condition of pressure balance obtains and the valve is closed by spring pressure when the inlet pressure is released to trap the fluid in the line and permit adjustment of the brakes. Should fluid have been added to compensate for heat expansion, fluid may escape as the brake drum cools by forcing open the valve means 36 until the required pressure balance is achieved.

Abstract: 883,835. Refining ferrous metal. BRITISH OXYGEN CO. Ltd. May 4, 1960 [May 6, 1959], No. 15530/59. Class 72. A process of refining molten ferrous metal comprises allowing the molten metal to fall through a reaction space in contact with an oxidising gas, the injector action of the oxidising gas withdrawing, from a point remote from the gas inlet, at least a part of the fume produced and returning it to the reaction space. The oxidising gas may be oxygen or a gas rich in oxygen and may contain slag forming substances in suspension. As shown, molten metal falls through holes in a plate 14, forming the bottom of a crucible 13, into a reaction space 12 where it meets jets of oxygen from nozzles 18 arranged to act as injectors in ducts 15 to which are secured ducts 16 attached to radial ducts 17 ending in the reaction space. The ducts may be formed in the brickwork of the reaction space. The nozzles 18 may be adjustable to vary the injector action and, if desired, provision may be made for the addition of more oxygen into the chamber or the ducts. The oxidising gas may flow in counter current to the metal. Specifications 790,790, 817,783 and 835,159 are referred to.

Abstract: 242,227. Dorogi, L., Dorogi, I., and Dorogi & Co. Rubber Goods Factory, Ltd., Dr. Oct. 29, 1924, [Convention date]. Moulding indiarubber hollow-ware. - A die is introduced between sheets of rubber which are to be stamped out to prevent the sheets adhering to each other at the cut edges. The process is described with reference to the manufacture of inflatable figures having members in more than. one plane. An aperture 9 is punched out of two sheets 7, 8, after which a die 13 having a gup 14 is introduced between the sheets, and two additional sheets 10, 11 are applied, the whole being pressed between flat plates to an outline 12. Pairs of legs &c. are produced by the sheets 7, 11 and 8, 10 and superfluous members are cut away, the edges then being united and the whole figure vulcanized. In a modification, two dies, or a die-plate having cutting edges on its upper and lower surfaces, are used and no superfluous material is left. Alternatively, a flat plate may take the place of the separating die, the cutting being ejected by two external dies which are pressed on to the sheets. A punch 15 produces the aperture 9 before the application of the sheets 10, 11. The article produced thus consists of two side sheets connected by a ring formed of two flat rings joined together at their inner edges, each ring being joined at its outer edge to the edge of one side ebeet.
